MODIFIED EXAMPLES

-   -   <<Natural Transmission Method>>

FIG. 1 is a view showing a situation of behavior support using awearable device according to one embodiment of the present technology.

The wearable device 1 wearable on an ear of a user is an agent devicethat performs behavior support for a user as a wearer. The behaviorsupport by the wearable device 1 is performed so as to detect a contextof the user and transmit an action corresponding to the context by amethod suitable for the context and the content of the action.

Here, the context of the user includes at least one of the surroundingenvironment of the user wearing the wearable device 1, the feeling ofthe user, the situation of the user, the feelings of other people aroundthe user, or the situations of the other people around the user. Thewearable device 1 has a function of generating information to be usedfor detecting a surrounding environment or the like by using a mountedcamera or various sensors.

Transmission of an action by the wearable device 1 is performed by amethod using wind, a method using vibration, or a method using soundsuch that people around the user is not aware of it.

For example, the transmission of an action by using wind is performed soas to blow wind having a temperature corresponding to an action to betransmitted, to the vicinity of the user's face or the like. Further,the transmission of an action by using vibration is performed so as togenerate vibration having a pattern corresponding to an action to betransmitted. The transmission of an action by using sound is performedso as to output sound having a tone corresponding to an action to betransmitted, at low volume, from a speaker provided in the vicinity ofthe ear.

The wearable device 1 also has a function of sending wind of differenttemperatures, a function of vibrating in different patterns, and afunction of outputting sound of different tones from the speaker nearthe ear.

In such a manner, the wearable device 1 transmits an action suitable forthe context to the user in a natural way, to thus perform behaviorsupport. A natural transmission method means a transmission methodperformed such that people around the user do not notice thetransmission of an action.

For example, in a case where an action is transmitted by displaying amessage, this makes the user to be conscious of viewing the message.Depending on circumstances, the user does not want people around theuser to know that the user is viewing the message.

Further, in a case where an action is transmitted by using sound at highvolume in a quiet space or in a case where an action is transmitted in asituation where another person exists and in such a manner that theother person may notice the transmission of an action, the user may feelawkward.

Transmitting an action by a natural method such that people around theuser do not notice it can also be a so-called thoughtful transmissionway.

Further, the transmission of an action by the wearable device 1 isperformed by appropriately transmitting two opposite actions.

For example, as shown in FIG. 1, in a case where there is a piece ofcake in front of a user on a diet, two actions, i.e., an action of“refrain” and an action of “eat”, are transmitted. The former action isan action based on a goal, which is a diet, and the latter action is anaction being against the goal. Those actions can be actions havingopposite content.

The illustration of an angel shown in FIG. 1 represents an image toencourage the achievement of the goal by transmitting an action of“refrain”. Meanwhile, the illustration of a devil represents an image totempt the user to do an action contrary to the achievement of the goalby transmitting an action of “eat”.

It should be noted that the fact that a diet is the goal is set by theuser as a situation of the user, for example. Further, the fact thatthere is a piece of cake in front of the user is identified by, forexample, analyzing an image captured by a camera of the wearable device1.

In such a manner, the wearable device 1 is capable of transmitting twoopposite actions as actions suitable for the context of the user.

For example, it is thought that even if a user has a strong will to takeone of actions, the user potentially has a willingness to take an actioncontrary to the one action. Presenting an action following such apotential willingness and giving the user a push can be a thoughtfultransmission way.

Further, a user having a stronger will is less willing to take an actionthat goes against his/her will. Thus, when such a user having a strongwill to take one of the actions is caused to take another actioncontrary to the one action, the user may discover something new. Even inthe sense that an action leading to a discovery of something new ispresented as an option, transmitting two opposite actions can be athoughtful transmission way.

Operations of respective devices that transmit the above-mentionedactions suitable for the context of the user in a thoughtfultransmission way will be described later with reference to flowcharts.

First Embodiment Transmission of Action Suitable for Context 1.Configuration Example of Information Processing System

-   FIG. 2 is a view showing a configuration example of an information    processing system.

The information processing system of FIG. 2 is configured by connectingthe wearable device 1 and a control server 2 to each other via a network3 such as the Internet.

The wearable device 1 generates images captured by cameras and sensordata detected by various sensors as context information to be used forrecognizing a context of the user, and sends the context information tothe control server 2.

Further, the wearable device 1 receives a control signal sent from thecontrol server 2 in response to the sending of the context information.The control signal is information representing at least the content ofan action to be transmitted to the user and a transmission method forthe action. The wearable device 1 transmits an action determined by thecontrol server 2 to the user by a method determined by the controlserver 2 according to the control signal.

The control server 2 receives the context information sent from thewearable device 1 and recognizes the context of the user on the basis ofthe context information. Further, the control server 2 determines anaction corresponding to the recognized context and also determines atransmission method for an action.

In the control server 2, a database in which an action and atransmission method are registered in association with each context ismanaged. The control server 2 sends the control signal, which representsthe content of the determined action and the transmission methodsuitable for the context and the action, to the wearable device 1 tothus control transmission of the action to the user.

As will be described later, an information processing system to whichthe present technology is applied can be achieved by a single wearabledevice 1. A plurality of wearable devices similar to the wearable device1 may be connected to the network 3.

1-1. Configuration Example of Wearable Device 1

-   FIGS. 3 and 4 are views each showing an example of an outer    appearance of the wearable device 1.

The casing of the wearable device 1 is configured by an ear hook portion11A and an arm portion 11B that are integrally formed, the ear hookportion 11A having an inverted triangular shape with the gently roundedcorners, the arm portion 11B having an arrow shape whose width isgradually narrowed from the base toward the tip.

The ear hook portion 11A has an opening 11 a having substantially thesame shape as that of the ear hook portion 11A. The wearable device 1 isworn by passing the left ear through the opening 11 a. In FIG. 3, theleft side corresponds to the front side of the face of the user, and theright side corresponds to the back side of the head. The surface shownin FIG. 3 is the outer surface of the casing, and the rear surface isthe inner surface of the casing.

An edge portion 22 surrounding the opening 11 a is made of a flexiblematerial such as a low resilient urethane material. The edge portion 22softens by body temperature, so that the shape and size of the opening11 a can be appropriately deformed. The edge portion 22 is deformed, andthus the opening 11 a is widened to adapt to the ear or caught to fitthe ear.

The edge portion 22 may be made of a shape-memory alloy that is deformedinto a predetermined shape by body temperature. The entire ear hookportion 11A can also be made of a low resilient urethane material or ashape-memory alloy.

A speaker 23 is provided at a position near the front of the edgeportion 22. When the wearable device 1 is worn, the speaker 23 ispositioned near the cavity of the ear.

The arm portion 11B is formed to be gently curved toward the inside ofthe wearable device 1. When the wearable device 1 is worn, the tip ofthe arm portion 11B is positioned near the left eye of the user. A frontimaging camera 21 as a camera for imaging the front is provided outsidea V-shaped portion at the tip of the arm portion 11B (FIG. 3). Aline-of-sight detection camera 24 as a camera for detecting the line ofsight, and a projection unit 25 are provided inside the V-shaped portionat the tip of the arm portion 11B (FIG. 4).

For example, when an image captured by the line-of-sight detectioncamera 24 is analyzed, a motion of the line of sight is detected.Further, a region being viewed by the user in an image captured by thefront imaging camera 21 is identified on the basis of a direction of thedetected line of sight.

The projection unit 25 is a retina-direct-projection display module. Theprojection unit 25 projects an image on the retina of the left eye ofthe user to present information.

FIG. 5 is a view showing another example of the outer appearance of thewearable device 1.

In the example of FIG. 5, an attachment portion 31 is provided at aposition near the rear side of the ear hook portion 11A. A small robotarm is attachable to the attachment portion 31. The robot arm attachedto the attachment portion 31 is used for transmitting an action.

In other words, transmission of an action by the wearable device 1 isalso performed by a method using the drive of the robot arm. The robotarm is attached such that the tip thereof pinches the hair or a part ofthe ear of the user. The wearable device 1 performs operations such aspulling the hair and pulling the ear by using the robot arm andtransmits an action to the user.

The tip of the robot arm may be caused to reach the neck or back of theuser and push it, thus transmitting an action. The robot arm isdisclosed in, for example, Japanese Patent Application Laid-open No.2002-6924.

An outlet 32 is provided at a position near the upper side of the earhook portion 11A. An action is transmitted as described above by usingwind to be discharged from the outlet 32. A mechanism to blow windhaving different temperatures is disclosed in, for example, JapanesePatent Application Laid-open No. 2006-136628. An action may betransmitted by using wind with the amount corresponding to an action tobe transmitted.

An operation unit 33 is provided at a position near the lower side ofthe ear hook portion 11A. The operation unit 33 is, for example, a touchsensor and detects an operation of the user. When the wearable device 1is worn, the operation unit 33 is positioned near the ear lobe. The usercan perform various operations by a motion such as a touch to the earlobe. A motion of the user to touch the ear lobe may be detected with acamera, an infrared ray sensor, or the like, so that the operation canbe performed.

The positions of the attachment portion 31, the outlet 32, and theoperation unit 33 shown in FIG. 5 can be changed to any positions.Hereinafter, description will be given assuming that the wearable device1 has the configuration shown in FIG. 5. A robot arm is attached to theattachment portion 31.

FIG. 6 is a block diagram showing a configuration example of thewearable device 1.

The wearable device 1 is configured by connecting the front imagingcamera 21, the line-of-sight detection camera 24, the operation unit 33,a sensor unit 62, a storage unit 63, an output unit 64, and an I/F unit65 to a controller 61.

The controller 61 includes a CPU, a ROM, a RAM, and the like. Thecontroller 61 executes a predetermined program by the CPU and controlsthe whole operations of the wearable device 1.

The front imaging camera 21 images the front of the user wearing thewearable device 1 and outputs an image obtained by imaging to thecontroller 61. The image captured by the front imaging camera 21 may bea still image or a moving image.

The line-of-sight detection camera 24 images a range including the lefteye of the user wearing the wearable device 1 and outputs an imageobtained by imaging to the controller 61.

The operation unit 33 detects an operation of the user and outputs asignal indicating the content of the operation to the controller 61. Theoperation unit 33 may be configured by not only a touch sensor providedin the vicinity of the ear lobe of the user but also a touch sensor or abutton provided at another position.

The sensor unit 62 is configured by various sensors such as anacceleration sensor, a gyroscope sensor, a GPS sensor, and a biosensor.The biosensor configuring the sensor unit 62 includes a body temperaturesensor, a heart rate sensor, and the like. The biosensor may include asensor that detects brain waves such as alpha waves and beta waves. Forexample, the degree of concentration or the like of the user is detectedfrom a measured value measured by the biosensor. The sensor unit 62outputs sensor data indicating measured values measured by therespective sensors to the controller 61.

The storage unit 63 is configured by a flash memory or the like. Thestorage unit 63 stores various types of data.

The output unit 64 includes the speaker 23, the projection unit 25, ablower unit 91, a thermal adjustment unit 92, a vibration unit 93, and arobot arm unit 94.

The speaker 23 outputs sound or sound effects.

The projection unit 25 applies light and projects an image onto theretina of the eye of the user.

The blower unit 91 is configured by a small fan or the like and sendswind from the outlet 32.

The thermal adjustment unit 92 is configured by a small module to be aheat generation source and a cooling module. The heat generated by thethermal adjustment unit 92 and the temperature of wind sent from theblower unit 91 by a cooling function of the thermal adjustment unit 92are adjusted.

The vibration unit 93 generates vibration.

The robot arm unit 94 is a robot arm attached to the attachment portion31. The robot arm unit 94 performs various operations under the controlof the controller 61.

The I/F unit 65 are an interface for near field communication such asBluetooth (registered trademark) or a wireless LAN, and an interface forwireless communication using a mobile communication system (WAN) such as3G or 4G. The I/F unit 65 performs communication with an external devicesuch as the control server 2.

In the wearable device 1 having the above-mentioned configuration, theCPU of the controller 61 executes a predetermined program, and thus acontext information generation unit 81 and a transmission controller 82are achieved.

The context information generation unit 81 acquires a front imagecaptured by the front imaging camera 21, an image captured by theline-of-sight detection camera 24, and sensor data supplied from thesensor unit 62 and generates context information.

As described above, the context includes at least one of the surroundingenvironment of the user wearing the wearable device 1, the feeling ofthe user, the situation of the user, the feelings of other people aroundthe user, or the situations of the other people around the user.

For example, the context information generation unit 81 analyzes theimage captured by the line-of-sight detection camera 24 to detect theline of sight of the user, and identifies a region viewed by the user inthe entire front image. The context information generation unit 81generates context information including the front image, the informationof the region viewed by the user, and the sensor data.

The front image and the information of the region viewed by the user areinformation that can be used for identifying the surrounding environmentof the user, the situation of the user, the feelings of other peoplearound the user, and the situations of the other people around the user.

For example, when the front image is analyzed, the surroundingenvironment of the user, e.g., “the user stays outside”, can beidentified.

Further, when an image of a person within the region viewed by the useramong people shown in the front image is analyzed, the situation of theuser, e.g., “the user is talking with another person”, can beidentified.

When the front image is analyzed, the feelings of the other people,e.g., “people around the user are delighted”, or the situations of theother people, e.g., “people around the user are running”, can beidentified.

Meanwhile, the sensor data supplied from the sensor unit 62 isinformation that can be used for identifying the feeling of the userwearing the wearable device 1 and the situation of the user.

For example, the feeling of the user, e.g., “the user is angry”, can beidentified from the brain waves.

Further, the situation of the user, e.g., “the user is walking” or “theuser is jogging”, can be identified from a body temperature, a heartrate, or vibration (acceleration, angular velocity).

In such a manner, the context information generated by the contextinformation generation unit 81 is information used for recognizing thesurrounding environment of the user, the feeling of the user, thesituation of the user, the feelings of other people around the user, andthe situations of the other people around the user. The contextinformation generation unit 81 controls the I/F unit 65 to send thegenerated the context information to the control server 2.

The transmission controller 82 controls the I/F unit 65 to receive acontrol signal sent from the control server 2. The transmissioncontroller 82 controls each block of the output unit 64 according to thecontrol signal and transmits an action determined by the control server2 to the user by a transmission method determined by the control server2.

1-2. Configuration Example of Control Server 2

-   FIG. 7 is a block diagram showing a configuration example of the    control server 2.

The control server 2 is configured by connecting an I/F unit 112 and anaction information storage unit 113 to a controller 111.

The controller 111 includes a CPU, a ROM, a RAM, and the like. Thecontroller 111 executes a predetermined program by the CPU and controlsthe whole operations of the control server 2.

The I/F unit 112 is an interface that performs wireless or wiredcommunication. The I/F unit 112 performs communication with the wearabledevice 1 via the network 3.

The action information storage unit 113 is configured by an HDD or anSSD. The action information storage unit 113 stores action information.The action information indicates a correspondence relationship between acontext, an action corresponding to the context, and a transmissionmethod suitable for the context and the action. The action informationstorage unit 113 configures a database of the action information.

In the control server 2, the CPU of the controller 111 executes apredetermined program, and thus a context recognition unit 121, anaction determination unit 122, and a control signal generation unit 123are achieved.

The context recognition unit 121 controls the I/F unit 112 to acquirecontext information sent from the wearable device 1. Further, thecontext recognition unit 121 recognizes the context of the user on thebasis of the acquired context information. The context recognition unit121 has information for recognizing the context, such as data forrecognizing an object appearing in an image or data for detecting apattern of sensor data.

The action determination unit 122 refers to an action database managedby the action information storage unit 113 to determine an actioncorresponding to the context recognized by the context recognition unit121 and a transmission method therefor.

The control signal generation unit 123 generates a control signalindicating the action and the transmission method determined by theaction determination unit 122. The control signal generation unit 123controls the I/F unit 112 to send the control signal to the wearabledevice 1.

FIG. 8 is a diagram showing an example of action information.

The example of FIG. 8 shows action information regarding three contextsof context IDs 1, 2, and 3.

The context of the context ID 1 is a context selected under thecondition that it is recognized that there is a piece of cake.

It is recognized that there is a piece of cake, for example, when apiece of cake appears in a region viewed by the user in the front imageincluded in the context information. The fact that there is a piece ofcake is, for example, a recognition result of the surroundingenvironment of the user.

When it is recognized that there is a piece of cake, “refrain fromeating” is determined as an action to be transmitted to the user.Further, a method of blowing warm wind and using sound of an angeliclimpid tone is determined as a transmission method for “refrain fromeating”.

The context of the context ID 2 is a context selected under thecondition that it is recognized that the user does not focus on theclass.

It is recognized that the user is in class, for example, when the frontimage included in the context information is analyzed and a featurerepresenting that the user is in class is detected. Further, it isrecognized that the user does not focus on the class, for example, whenthe sensor data included in the context information shows a measuredvalue that appears when the user does not focus. The fact that the userdoes not focus on the class is, for example, a recognition result of thesurrounding environment of the user and the situation of the user.

When it is recognized that the user does not focus on the class, “focus”is determined as an action to be transmitted to the user. Further, amethod of blowing cool wind to reduce sleepiness is determined as atransmission method for “focus”.

The context of the context ID 3 is a context selected under thecondition that it is recognized that the other person looks tough.

It is recognized that there is other person, for example, when the frontimage included in the context information is analyzed and a featurerepresenting that the user is talking with other person is detected.Further, it is recognized that the other person looks tough on the basisof, for example, the height of a person appearing in the region viewedby the user or the size of the arm of the person. The fact that theother person looks tough is, for example, a recognition result of thesurrounding environment of the user and the situations of other peoplearound the user.

When it is recognized that the other person looks tough, “run away” isdetermined as an action to be transmitted to the user. Further, a methodof pulling the hair with the robot arm unit 94 is determined as atransmission method for “run away”.

In the action database of FIG. 8, a single action and a singletransmission method are managed in association with a single context. Inthe example of FIG. 8, three pieces of action information are shown, butmore pieces of action information are registered in the action database.

<3. Operation of Information Processing System>

Here, an operation of the information processing system of FIG. 2 willbe described. As shown in FIG. 8, it is assumed that a single action anda single transmission method are managed in association with a singlecontext.

First, the sending processing of the wearable device 1 will be describedwith reference to a flowchart of FIG. 9.

The processing of FIG. 9 is performed when the user is wearing thewearable device 1. It is assumed that the user performs daily activitiessuch as walking around the city and going to school while wearing thewearable device 1. During those activities, the imaging by the frontimaging camera 21 and the line-of-sight detection camera 24 and themeasurement by the sensor unit 62 are repetitively performed.

In Step S1, the context information generation unit 81 acquires a frontimage captured by the front imaging camera 21, an image captured by theline-of-sight detection camera 24, and sensor data supplied from thesensor unit 62.

In Step S2, the context information generation unit 81 generates contextinformation on the basis of the captured images and the sensor data.

In Step S3, the context information generation unit 81 sends thegenerated context information to the control server 2 and terminates theprocessing. The above-mentioned processing is repetitively performed atpredetermined periods.

Next, the control processing of the control server 2 will be describedwith reference to a flowchart of FIG. 10.

The processing of FIG. 10 is started when the processing of FIG. 9 isperformed by the wearable device 1 and the context information is sentfrom the wearable device 1.

In Step S11, the context recognition unit 121 receives and acquires thecontext information sent from the wearable device 1.

In Step S12, the context recognition unit 121 recognizes the context onthe basis of the acquired context information.

In Step S13, the context recognition unit 121 determines whether aprescribed context registered in the action database is recognized ornot.

When the context recognition unit 121 determines in Step S13 that aprescribed context is not recognized, the processing returns to Step S11and the following processing is repeated. Meanwhile, when the contextrecognition unit 121 determines in Step S13 that a prescribed context isrecognized, the processing proceeds to Step S14.

In Step S14, the action determination unit 122 refers to the actiondatabase managed by the action information storage unit 113 anddetermines an action corresponding to the context recognized by thecontext recognition unit 121.

In Step S15, the control signal generation unit 123 generates a controlsignal that indicates the action and transmission method determined bythe action determination unit 122. The transmission method determined bythe action determination unit 122 is a method managed in the actiondatabase as a method suitable for the context and the actioncorresponding thereto.

In Step S16, the control signal generation unit 123 sends the controlsignal to the wearable device 1 and terminates the processing.

Next, the action transmission processing of the wearable device 1 willbe described with reference to a flowchart of FIG. 11.

The processing of FIG. 11 is started when the processing of FIG. 10 isperformed by the control server 2 and a control signal is sent from thecontrol server 2.

In Step S31, the transmission controller 82 receives and acquires thecontrol signal sent from the control server 2.

In Step S32, the transmission controller 82 controls each unit of theoutput unit 64 according to the control signal, to transmit an actiondetermined by the control server 2 to the user by a transmission methoddetermined by the control server 2, and terminates the processing.

The series of processing described above allows an action correspondingto the context of the user to be transmitted in a natural way such thatpeople around the user do not notice it.

For example, when the context of “there is a piece of cake” isrecognized, “refrain from eating” is determined as an actioncorresponding to the context in the control server 2. Further, atransmission method suitable for the context of “there is a piece ofcake” and an action of “refrain from eating”, a method of blowing warmwind and using sound of an angelic limpid tone is determined. Thecontrol server 2 sends a control signal indicating the content describedabove to the wearable device 1.

In the wearable device 1, the blower unit 91 and the thermal adjustmentunit 92 are controlled to blow warm wind to the use's face or the likeaccording to the control signal. Further, the speaker 23 is controlledto output sound of an angelic limpid tone, e.g., “Don't eat it.”, to theear.

For example, when the user finds a shelf on which pieces of cake are putduring shopping in a supermarket, an action of “refrain from eating” isto be transmitted to the user in such a manner that people around theuser do not notice it.

If the sound, e.g., “Don't eat it.”, is output such that people aroundthe user hear it in order to transmit an action of “refrain fromeating”, the people around the user may know that the user is on a dietand the user may feel awkward. In such a manner, transmitting an actionin a natural way can prevent the user from feeling awkward.

Transmitting an action of “refrain from eating” without causing the userto feel awkward can be a thoughtful transmission way.

Second Embodiment Transmission of Two Opposite Actions

-   As described with reference to FIG. 1, a case where two opposite    actions are transmitted will be described. Description overlapping    with the above-mentioned description will be omitted appropriately.

FIG. 12 is a diagram showing another example of the action information.

In the example of FIG. 12, two actions and transmission methods aremanaged in association with each of three contexts of the context IDs 1,2, and 3.

Two actions of “refrain from eating” and “eat” are associated with thecontext of the context ID 1 to be selected under the condition that itis recognized that there is a piece of cake. When it is recognized thatthere is a piece of cake, two opposite actions of “refrain from eating”and “eat” are determined as actions to be transmitted to the user.

Further, a method of blowing warm wind and using sound of an angeliclimpid tone is determined as a transmission method for “refrain fromeating”. Meanwhile, a method of blowing cool wind and using sound of adevil tone is determined as a transmission method for “eat”. Adifference in tone is expressed by using, for example, the frequency ofvoice, rhythm, enunciation, a difference in gender of a speaker(man/woman), and the like.

Two actions of “focus” and “fall asleep” are associated with the contextof the context ID 2 to be selected under the condition that it isrecognized that the user does not focus on the class. When it isrecognized that the user does not focus on the class, two oppositeactions of “focus” and “fall asleep” are determined as actions to betransmitted to the user.

Further, a method of blowing cool wind to reduce sleepiness isdetermined as a transmission method for “focus”. Meanwhile, a method ofblowing warm wind is determined as a transmission method for “fallasleep”.

Two actions of “run away” and “stand against” are associated with thecontext of the context ID 3 to be selected under the condition that itis recognized that the other person looks tough. When it is recognizedthat the other person looks tough, two opposite actions of “run away”and “stand against” are determined as actions to be transmitted to theuser.

Further, a method of pulling the hair of the user with the robot armunit 94 is determined as a transmission method for “run away”.Meanwhile, a method of pushing the back of the user with the robot armunit 94 is determined as a transmission method for “stand against”.

In such a manner, in the control server 2, the two actions and therespective actions are managed in association with the single context.Three or more actions and transmission methods for the respectiveactions may be managed in association with the single context.

For example, the transmission method for “refrain from eating”, i.e.,the method of blowing warm wind and using sound of an angelic limpidtone, expresses encouragement for the action that suits a goal or adiet, and is a method suitable for the action. Further, the transmissionmethod for “eat”, i.e., the method of blowing cool wind and using soundof a devil tone, expresses temptation for the action that goes againstthe goal, and is a method suitable for the action.

Since those actions are determined according to the respective contexts,each of the transmission methods managed in the action database is amethod suitable for a context and an action corresponding to thecontext.

Next, the control processing of the control server 2 will be describedwith reference to a flowchart of FIG. 13.

The processing of FIG. 13 is started when the processing of FIG. 9 isperformed by the wearable device 1 and the context information is sentfrom the wearable device 1.

In Step S51, the context recognition unit 121 receives and acquires thecontext information sent from the wearable device 1.

In Step S52, the context recognition unit 121 recognizes the context onthe basis of the acquired context information.

In Step S53, the context recognition unit 121 determines whether aprescribed context registered in the action database is recognized ornot. When the context recognition unit 121 determines in Step S53 that aprescribed context is recognized, the processing proceeds to Step S54.

In Step S54, the action determination unit 122 refers to the actiondatabase managed by the action information storage unit 113 anddetermines a first action corresponding to the context recognized by thecontext recognition unit 121 and a transmission method therefor. Of thetwo opposite actions, one of the actions and a transmission methodtherefor are determined.

In Step S55, the control signal generation unit 123 generates a controlsignal indicating the first action and the transmission method that aredetermined by the action determination unit 122.

In Step S56, the control signal generation unit 123 sends the controlsignal to the wearable device 1.

In Step S57, the action determination unit 122 determines a secondaction corresponding to the context recognized by the contextrecognition unit 121 and a transmission method therefor. Of the twoopposite actions, the other action and a transmission method thereforare determined.

In Step S58, the control signal generation unit 123 generates a controlsignal indicating the second action and the transmission method that aredetermined by the action determination unit 122.

In Step S59, the control signal generation unit 123 sends the controlsignal to the wearable device 1.

The wearable device 1 that has received the control signals sent in StepS56 and Step S59 performs, at respective timings, processing similar tothe processing described with reference to FIG. 11, and transmits eachof the two opposite actions to the user.

This achieves a thoughtful transmission way in which two oppositeactions are transmitted in a natural way.

In the example of FIG. 13, the wearable device 1 is notified of the twoactions by using the control signals different from each other, but thewearable device 1 is notified of the two actions collectively by asingle control signal.

Further, in a case where the two actions are managed in association witha single context, one of the actions may be transmitted.

Third Embodiment Transmission of Action Opposite to User's Behavior

-   In a case where the two actions are managed in association with a    single context, an action opposite to the action that the user tries    to take may be transmitted.

For example, the two actions of “refrain from eating” and “eat” aremanaged for the context of “there is a piece of cake”. However, when itis predicted that the user refrains from eating the piece of cake, theaction of “eat” is transmitted.

Meanwhile, when it is predicted that the user tries to eat the piece ofcake, the action of “refrain from eating” is transmitted. What behaviorto be taken by the user for the current context is predicted bymonitoring before transmitting an action, and an action to betransmitted is determined according to a monitoring result.

This enables a thoughtful transmission way such as presenting an actionfollowing a potential willingness in a natural way and giving the user apush.

Next, the control processing of the control server 2 will be describedwith reference to a flowchart of FIG. 14.

In Step S71, the context recognition unit 121 receives and acquires thecontext information sent from the wearable device 1.

In Step S72, the context recognition unit 121 recognizes the context onthe basis of the acquired context information.

In Step S73, the context recognition unit 121 determines whether aprescribed context registered in the action database is recognized ornot. When the context recognition unit 121 determines in Step S73 that aprescribed context is recognized, the processing proceeds to Step S74.

In Step S74, the context recognition unit 121 predicts a user's behaviorby monitoring on the basis of the context information sequentially sentfrom the wearable device 1. In the wearable device 1, the contextinformation is repetitively sent. Since an action is not yettransmitted, the user takes an action corresponding to the currentcontext according to the user's will.

In Step S75, the action determination unit 122 determines whether theuser tries to take the first action or not in the two actionscorresponding to the context recognized by the context recognition unit121, on the basis of a monitoring result.

In Step S75, when determining that the user tries to take the firstaction, the action determination unit 122 determines the second actionas an action to be transmitted to the user in Step S76. Of the twoactions managed in the action database as actions corresponding to thecurrent context, one action different from the other action that theuser tries to take is determined. Further, the action determination unit122 refers to the action database to determine a transmission method forthe second action.

In Step S77, the control signal generation unit 123 generates a controlsignal indicating the second action and the transmission method that aredetermined by the action determination unit 122.

In Step S78, the control signal generation unit 123 sends the controlsignal to the wearable device 1.

Meanwhile, in Step S75, when the action determination unit 122determines that the user tries to take the second action instead of thefirst action, the processing proceeds to Step S79.

In Step S79, the action determination unit 122 determines the firstaction as an action to be transmitted to the user. In this case as well,of the two actions managed in the action database as actionscorresponding to the current context, one action different from theother action that the user tries to take is determined. Further, theaction determination unit 122 refers to the action database to determinea transmission method for the first action.

In Step S80, the control signal generation unit 123 generates a controlsignal indicating the first action and the transmission method that aredetermined by the action determination unit 122. The control signalgenerated here is sent to the wearable device 1 in Step S78.

In the wearable device 1, processing similar to the processing describedwith reference to FIG. 11 is performed, and an action opposite to theaction that the user tries to take is transmitted as an actioncorresponding to the current context.

By the processing described above, when it is recognized that there is apiece of cake, if the user refrains from eating the piece of cake, anaction of “eat” is determined and transmitted by using warm wind andsound of an angelic limpid tone. Conversely, if the user tries to eatthe piece of cake, an action of “refrain from eating” is determined andtransmitted by using cool wind and sound of a devil tone.

Further, when it is recognized that the user does not focus on theclass, if the user tries to focus on the class, an action of “fallasleep” is determined and transmitted by using warm wind. Conversely, ifthe user tries to fall asleep, an action of “focus” is determined andtransmitted by using cool wind.

When it is recognized that the other person looks tough, if the usertries to run away, an action of “stand against” is determined andtransmitted by pushing the back with the robot arm unit 94. Conversely,if the user tries to stand against the other person, an action of “runaway” is determined and transmitted by pulling the hair with the robotarm unit 94.

This also achieves a thoughtful transmission way in which two oppositeactions are transmitted in a natural way.

Fourth Embodiment Method of Determining Action To Be Transmitted

-   It is assumed that an action is determined on the basis of the    context information generated by the wearable device 1, but the    method of determining an action to be transmitted to the user may be    another method. An action determined by another method is also    transmitted in a natural way by using various methods as described    above.

FIG. 15 is a diagram showing an example of the action information.

The context of the context ID 4 is a context selected under thecondition that it is recognized that a sender of e-mail is angry beforethe e-mail is opened (before the user reads the e-mail).

In this example, the feeling or situation of the sender is recognizedfrom a message included in the e-mail to the user of the wearable device1, and an action corresponding to a recognition result is determined.The feeling or situation of the sender corresponds to the feelings ofother people around the user or the situations of other people aroundthe user and is included in the above-mentioned context.

The e-mail to the user of the wearable device 1 is acquired by thecontrol server 2 and the content thereof is analyzed. In the controlserver 2, information for recognition, such as key words (negativewords/positive words) representing the feelings or situations of thesender, is managed. When receiving the e-mail to the user of thewearable device 1, the control server 2 performs natural languageprocessing to extract key words and performs recognition of the feelingsor situations of the sender on the basis of the frequencies of thosewords.

When it is recognized that the sender of the e-mail is angry, “replyimmediately” is determined as an action to be transmitted to the user.Further, a method of generating vibration having a prescribed patternand using sound of a quavering tone is determined as a transmissionmethod for “reply immediately”.

In such a manner, the context of the user can be determined also by amethod different from the method using the context information generatedby the wearable device 1.

It should be noted that the context may be recognized by using not onlythe message included in the e-mail but also a message of SNS (SocialNetworking Service) or the like as the message to the user of thewearable device 1.

Next, the control processing of the control server 2 will be describedwith reference to a flowchart of FIG. 16.

In Step S91, the context recognition unit 121 receives and acquirese-mail to the user of the wearable device 1. The e-mail to the user ofthe wearable device 1 may be acquired from an apparatus regularly usedby the user for sending/receiving e-mail, or may be acquired from a mailserver used by the user.

In Step S92, the context recognition unit 121 analyzes the content ofthe acquired e-mail and recognizes the context.

In Step S93, the context recognition unit 121 determines whether aprescribed context registered in the action database, e.g., the senderof the e-mail is angry, is recognized or not.

When the context recognition unit 121 determines that a prescribedcontext is not recognized in Step S93, the processing returns to StepS91 and the following processing is repeated. Meanwhile, when thecontext recognition unit 121 determines that a prescribed context isrecognized in Step S93, the processing proceeds to Step S94.

In Step S94, the action determination unit 122 refers to the actiondatabase managed by the action information storage unit 113 anddetermines an action and a transmission method therefor that aresuitable for the prescribed context. When the fact that “the sender ofthe e-mail is angry” is recognized, an action of “reply immediately” anda transmission method using vibration and sound of a quavering tone aredetermined.

In Step S95, the control signal generation unit 123 generates a controlsignal indicating the action and the transmission method that aredetermined by the action determination unit 122.

In Step S96, the control signal generation unit 123 sends the controlsignal to the wearable device 1.

In the wearable device 1 that has received the control signal,processing similar to the processing described with reference to FIG. 11is performed, and “reply immediately” is transmitted to the user.

This allows the user of the wearable device 1 to recognize the need to“reply immediately” as an action suitable for the current context beforeconfirming the content of the e-mail.

MODIFIED EXAMPLES 1. Example of Action

-   The actions described above as recognizable ones are examples. It is    also possible to cause other actions to be recognized on the basis    of the context information.

FIG. 17 is a diagram showing an example of the action information.

In the example of FIG. 17, a single action and a single transmissionmethod are managed in association with the context of a context ID 5.Further, two actions and transmission methods for the respective actionsare managed in association with the context of a context ID 6.

The context of the context ID 5 is a context selected under thecondition that it is recognized that a customer looking at a productdoes not have a willingness to buy it. The context of the context ID 5is recognizable, for example, when the user of the wearable device 1 isa salesperson for the product and is serving customers in a store.

It is recognized that a customer does not have a willingness to buy aproduct, when the front image included in the context information isanalyzed. For example, assuming that a person who is seen by the user ofthe wearable device 1 is a customer, when a direction of the face, amotion of the line of sight, or a facial expression of the customershows a peculiar pattern (feature) appearing when a customer does nothave a willingness to buy a product, it is recognized that the customerdoes not have a willingness to buy the product. The fact that thecustomer looking at a product does not have a willingness to buy it is,for example, a recognition result of the surrounding environment of theuser and the situations of other people around the user.

When it is recognized that the customer looking at a product does nothave a willingness to buy it, “serve another customer” is determined asan action to be transmitted to the user as a salesperson. Further, amethod using sound of a calm tone is determined as a transmission methodfor “serve another customer”.

The context of the context ID 6 is a context selected under thecondition that it is recognized that the user is tired from jogging.

It is recognized that the user is jogging, for example, when vibrationindicated by the sensor data included in the context information shows apeculiar pattern appearing during jogging. Further, it is recognizedthat the user is tired, for example, when the heart rate of the userindicated by the sensor data included in the context information shows apeculiar pattern appearing when the user is tired. The fact that theuser is tired from jogging is, for example, a recognition result of thesituation of the user.

When it is recognized that the user is tired from jogging, two oppositeactions of “try a little harder” and “rest” are determined as actions tobe transmitted to the user.

Further, a method of tapping the back of the user with the robot armunit 94 and using a male voice of a forceful tone is determined as atransmission method for “try a little harder”. Meanwhile, a method ofgently stroke the back of the user with the robot arm unit 94 and usinga female voice of a gentle tone is determined as a transmission methodfor “rest”.

In such a manner, it is possible to recognize various actions in thecontrol server 2.

When the relationship between the context and the action is not fixedand a certain context is recognized, a single action may be determinedfrom various actions at random and transmitted.

In this case, the user may be allowed to evaluate the action determinedat random. The evaluation of the action is performed by, for example,operating the operation unit 33 located near the ear lobe when the userwears the wearable device 1. The evaluation of the action input by theuser is used for determining an action when the same context isrecognized as the next context, such as a change in priority order.

The transmission method for each action can also be changed. Forexample, the action transmitted by the method using wind may betransmitted by a method using vibration, a method using sound, or amethod using the robot arm unit 94. In such a manner, the method usedfor transmitting an action can be changed and a combination thereof canalso be changed.

Further, it is possible to transmit an action by using various methodscapable of stimulating the five senses, such as a method using smell, amethod using water, and a method using heat. Transmission of an actionmay be performed by projecting videos or texts by the projection unit25.

2. Another Configuration Example of Information Processing System

-   FIG. 18 is a diagram showing a configuration example of the wearable    device 1 as an information processing system. The same configuration    as that described with reference to FIGS. 6 and 7 is denoted by the    same reference symbol. Overlapping description will be appropriately    omitted.

In the example of FIG. 18, the functions, which have been described asthose of the control server 2, are implemented in the wearable device 1.In other words, the CPU executes a predetermined program, and thus inaddition to the context information generation unit 81 and thetransmission controller 82, the context recognition unit 121, the actiondetermination unit 122, and the control signal generation unit 123 areachieved in the controller 61.

The context recognition unit 121 of the controller 61 acquires thecontext information generated by the context information generation unit81 and recognizes the context of the user.

The action determination unit 122 refers to the action database managedby the action information storage unit 113 formed in the storage unit 63to determine an action corresponding to the context recognized by thecontext recognition unit 121 and a transmission method therefor.

The control signal generation unit 123 generates a control signalindicating the action and the transmission method that are determined bythe action determination unit 122. The control signal generated by thecontrol signal generation unit 123 is supplied to the transmissioncontroller 82 and used for driving each unit.

In the wearable device 1 having the configuration of FIG. 18, each typeof processing including the recognition of a context, the determinationof an action corresponding to the context, and the determination of atransmission method, which have been described as those performed by thecontrol server 2, is performed. In such a manner, at least part of thefunctions of the control server 2 can be achieved in the wearable device1.

-   -   Shoulder-mounted Type

-   Hereinabove, the wearable device that performs the behavior support    for the user is assumed as an ear-hook device, but the form of the    wearable device is optional.

FIG. 24 is a view showing a mount example of another wearable device.

A wearable device 201 shown in FIG. 24 is a shoulder-mounted agentdevice. The wearable device 201 performs the behavior support for theuser as a wearer, in a similar manner as in the wearable device 1.

FIG. 25 is a view showing an example of an outer appearance of thewearable device 201.

The wearable device 201 has a substantially elliptical shape in planview and includes a casing 211 having a flat dome shape. At least partof the casing 211 is made of an elastic material. The casing 211 hasflexibility, bends by the user applying force from the upper surface orby its dead weight, and deforms as shown in FIG. 26 to become stable onthe shoulder of the user. Japanese Patent Application Laid-open No.2013-89219 discloses a device in which a deformable material is used,and the mechanism similar thereto can be employed for the casing 211.

The upper surface of the casing 211 has a gentle arc-shape. At thecenter of the upper surface of the casing 211, a display 221 having asubstantially elliptical shape in plan view is formed.

Three small circles are disposed side by side at a circumferentialportion of the display 221 on the front side. The center small circleconfigures a microphone 224, and the left and right small circlesconfigure speakers 225.

A section 221A having a horizontally elliptical shape when viewed fromthe front is formed on the front surface of the casing 211. Cameras222-1 and 222-2 that configure stereo cameras, and a projector 223 areprovided on the inner side of the section 221A.

FIG. 27 is a view showing another example of the outer appearance of thewearable device 201.

A small robot arm to be used for transmitting an action isattachable to the attachment portion 231. Further, an outlet 232 to bean outlet of wind used for transmitting an action is provided at acircumferential portion of the display 221 on the front side.

As with the case of the wearable device 1, the wearable device 201 ofFIG. 27 transmits an action by appropriately combining a method usingwind, a method using vibration, a method using sound, and a method usingthe robot arm. The wearable device 201 also has the same configurationas that described with reference to FIG. 6 or 18.

In such a manner, transmitting an action in a natural way by using windor the like can be performed by the shoulder-mounted wearable device201. With the shoulder-mounted wearable device 201, various actions canbe transmitted from a position near the ear or neck.

The wearable device 201 may be allowed to move in the vicinity of theshoulder. In this case, the user wears a pad made of a magnetic materialon the shoulder. The wearable device 201 generates a magnetic force andmoves within the range of the pad, thus transmitting various actions.The wearable device 201 may have a function of flying.

FIG. 28 is a view showing an outer appearance of the wearable device201. In FIG. 28, reference symbols representing the respective units areomitted. The same holds true for FIGS. 29 to 31. A of FIG. 28 shows thefront of the wearable device 201, and B of FIG. 28 shows the rear of thewearable device 201.

FIG. 29 is another view showing the outer appearance of the wearabledevice 201. A of FIG. 29 shows a left side surface of the wearabledevice 201, and B of FIG. 29 shows a right side surface of the wearabledevice 201. The casing 211 is formed into a gentle arc-shape when viewedfrom the side surface.

FIG. 30 is still another view showing the outer appearance of thewearable device 201. A of FIG. 30 shows a top surface of the wearabledevice 201, and B of FIG. 30 shows a bottom surface of the wearabledevice 201.

FIG. 31 is a perspective view showing the outer appearance of thewearable device 201. In FIG. 31, a gray-colored portion represents atransparent portion. A transparent cover is fitted into each of thesection 211A and the display 221.

The wearable device 201 has a function of presenting information by thedisplay 221 or the projector 223, a function of reproducing soundincluding voice, a function of imaging the front by the cameras 222-1and 222-2, and the like in addition to the behavior support functiondescribed above.

-   -   Neck-hanging Type

-   FIG. 32 is a view showing a configuration example of an outer    appearance of a wearable device 301 as a neck-hanging wearable    device.

The wearable device 301 is also an agent device that performs thebehavior support for the user as a wearer, in a similar manner as in thewearable device 1.

As shown in FIG. 32, the wearable device 301 has a substantiallyC-shaped outer appearance as a whole when viewed from the front. Thewearable device 301 is configured by providing a right-side unit 312 anda left-side unit 313 on the inner side of a band portion 311 atpositions close to the right tip and the left tip thereof, respectively,the band portion 311 being a curved, thin plate-like member.

The right-side unit 312 shown on the left side of FIG. 32 includes acasing having a width larger than the thickness of the band portion 311when viewed from the front, and is formed so as to swell from the innersurface of the band portion 311.

Meanwhile, the left-side unit 313 shown on the right side has a shapethat is substantially symmetrical to the right-side unit 312 such thatthe opening on the front of the band portion 311 is sandwichedtherebetween. The left-side unit 313 includes a casing having a widthlarger than the thickness of the band portion 311 when viewed from thefront, and is formed so as to swell from the inner surface of the bandportion 311, as in the right-side unit 312.

The wearable device 301 having such an outer appearance is worn aroundthe neck. When the wearable device 301 is worn, the inner side of theinnermost portion of the band portion 311 abuts on the back of the neckof the user, and the wearable device 301 takes a tilted posture. Whenviewed from the user, the right-side unit 312 is positioned on the rightside of the bottom of the neck of the user, and the left-side unit 313is positioned on the left side of the bottom of the neck of the user.

The wearable device 301 has an imaging function, a music reproductionfunction, a wireless communication function, a sensing function, and thelike, in addition to the behavior support function described above.

The user operates a button provided to the right-side unit 312 by, forexample, the right hand and operates a button provided to the left-sideunit 313 by, for example, the left hand while wearing the wearabledevice 301, and can thus execute functions thereof. Further, thewearable device 301 also implements a sound recognition function. Theuser can also operate the wearable device 301 by utterance.

By the music reproduction function of the wearable device 301, musicoutput from the speaker provided to the right-side unit 312 mainlyreaches the right ear of the user, and music output from the speakerprovided to the left-side unit 313 mainly reaches the left ear of theuser.

The user can run or ride a bicycle while wearing the wearable device 301and listening to music. Instead of music, sound of various pieces ofinformation such as news acquired via a network may be output.
